Pyridine → 4-chloro-N-(4-methyl-3-((3-(4-pyrimidinyl)-2-pyridinyl)amino)phenyl)benzenesulfonamide

Participants

Reaction Steps

To a solution of 4-methyl-N3-(3-pyrimidin-4-yl-pyridin-2-yl)-benzene-1,3-diamine (40 mg, 0.14 mmol) in CH2Cl2 (2.5 mL) was added pyridine (0.012 mL, 0.14 mmol) and 4-chlorobenzenesulfonyl chloride (30 mg, 0.14 mmol). The mixture was stirred overnight at RT, concentrated and purified by flash chromatography (0→50% EtOAc/n-Hexanes) to yield 4-chloro-N-(4-methyl-3-((3-(4-pyrimidinyl)-2-pyridinyl)amino)phenyl)benzenesulfonamide. MS m/z=452 [M+1]+. Calc'd for C22H18ClN5O2S: 451.94.
